The last 10 nights of Ramadan is said to be the most auspicious nights for the month. It is mentioned in the holy Quran that angels would come down to earth on one of those night, praying together with those who pray late in the nights.
Another practice associated with the last days of Ramadan is that of putting up lights around the house. From the twenty-seventh day of the month up to the Hari Raya (Eid) festival, if you walk through any Malay village you will find the houses lighted up with oil lamps, or coloured electric lamp. The occasion is known as "Malam Tujuh Likur" but it is not of Islamic origin even though the lights are said to welcome the angels who visit earth during this period.
Nevertheless, these displays of lights are very attractive especially in the villages. It also set the mood for the Hari Raya festival which is just a few days away.
